GEPRC Triple Feed Patch Array Antenna RP-SMA / SMA 5.8G 14dBi for FPV Racing Drone RC DIY Hobby Models

Introduction:

The Triple Feed Patch Array antenna is a directional circularly polarized antenna based on the original Triple Feed Patch antenna. It uses an array of seven coupled patches to achieve significantly higher gain. Since the beam width is quite narrow, this antenna is not recommended for general FPV, but it performs very well for long-haul flights.

	Simulation	Measured	Comment
Center frequency	5.8 GHz	5.8 GHz ± 100 MHz
Bandwidth	660 MHz (5.47 – 6.13 GHz)	950 MHz ± 100 MHz
Match	S11 < -30 dB, VSWR < 1.065	S11 < -20 dB, VSWR < 1.22
Axial ratio	1.05 (0.38 dB)	1.10 (0.83 dB)
Antenna gain	14.4 dBi	14.0 dBi
Half power beamwidth	30°	30°	Horizontal and vertical
Radiation efficiency	75%	74%

main feature:
Radiation efficiency is good. Most FR4-based patches are very efficient because FR4 is very lossy at 5.8 GHz. In addition, most array antennas have higher losses in the feed network. This design uses coupled patches to keep the feed network simple and reduce these losses.
Very good axial ratio, not only perpendicular to the patch but also eccentric.
High gain, but not higher than the theoretical gain of an array with 7 elements. This is because maximizing the gain results in high side lobes and poorer shaft ratios.
Very low side lobes, almost all of the energy is concentrated on the main lobe. This will increase the width of the main lobe but will increase some gain.
